Abstract: Aspects of the technology evaluate a client device query to identify an IP address-based estimated location of a mobile device (602, 604). One or more candidate wireless stations are selected in accordance with the IP-based estimated location and a location-relevant response to the query is also generated in accordance with the IP-based location. This information is transmitted to the mobile device. (606, 608). The mobile device compares the received information about the candidate wireless stations against one or more actual wireless stations with which the mobile device is in communication (506, 508). Log information is generated as a result of the comparison. The log information is anonymized and transmitted to the network without user ID or other client-identifiable information included in the log. (FIG. 1, 510) The received log information is then used to validate the initial estimated location. Aggregation of log information from multiple devices may be used in the validation process.

Abstract: Systems and methods for efficiently and securely requesting and receiving, from a remote service, data for multiple accounts associated with the same device or application. In one example, a client device is configured to request application data for all accounts associated with the device or application installation using a single remote procedure call, rather than requiring separate calls for each account, and to do so by providing a single identifier rather than including identifiers specific to each associated account. The remote service is further configured to return the requested information in a manner that obfuscates the account identifiers and thus limits their potential use if the communication is intercepted, such that the application data can be efficiently transmitted together even where security or other concerns would otherwise dictate that separate transmissions should be made for each account.
